2.5.1 Cell Structure

Vocabulary: cell wall, centriole, chloroplast, cytoplasm, endoplasmic reticulum, Golgi apparatus, lysosome, mitochondria, nuclear envelope, nucleolus, nucleus, organelle, plasma membrane, plastid, ribosome, vacuole, vesicle

Prior Knowledge Questions (Do these BEFORE using the Gizmo.)

1. What are some of the structures inside a cell that help it to live and perform its role in an organism? The cell membrane, nucleus, and the cytoplasm.

2. How do you think plant cells differ from animal cells? (Hint: What can plants do that animals cannot?) they cannot to photosynthesis, so that is what is different.

Gizmo Warm-up

The Cell Structure Gizmo™ allows you to look at typical animal and plant cells under a microscope. To start, click Sample to take a sample of an animal cell. Use the Zoom slider to see the cell at a magnification of 1000x (1000 times larger than normal).

1. Use the up/down and left/right sliders to manipulate the cell. Find the red arrow pointing to the centrioles. From the internet, find a new picture of a centriole and paste it here. Please include the web address you got it from.

2. Read the description of the centrioles. What is their function? There are two and during “cell division” they move apart to form or help form spindle, then distributes the chromosomes during cell division.

Activity A:

Animal cells Get the Gizmo ready:

• Check that an Animal cell is mounted on the microscope.

• Set the Zoom to 500x.

Question: Organelles are specialized structures that perform various functions in the cell. What are the functions of the organelles in an animal cell?

1. Label: Locate each organelle in the animal cell. Insert text boxes to label the organelles in the diagram below.

2. Match: Read about each organelle. Then match each organelle to its function/description.

H Cytoplasm

____ Lysosome

____ Mitochondria

____ Centriole

____ Endoplasmic reticulum...
